The WQS-G Stainless Steel Type Grinding Sewage Pump with cutting system for dirty water, designed primarily for industrial and civil applications, is equipped with a cast iron impeller with a cutter. Equipped with an overload protection device, it also features durability and safety in use. They are recommended for pumping wastewater from factories, construction sites and commercial facilities, drainage systems in municipal wastewater treatment plants: drainage stations in residential areas and municipal projects, or methane pools and field irrigation in rural areas. These series of sewage pumps are also designed for pumping dirty water with long fibers or solid particles; with an automatic thermal fuse, they easily cut and prevent impeller blockage due to entanglement, and are used in industrial, mining, and architectural applications.
|
Epoxy resin cable base The epoxy resin cable core can prevent moisture from entering the motor through the core. |
|
Automatic cutting of thermal protection If the engine is running under abnormal electrical power and temperature conditions, the thermal protection circuit breaker will activate and automatically cut off the power. The defender can be restored when the engine temperature returns to normal. Installed with a single-phase motor, three-phase without this fuse. |
|
Beautiful precision cast iron The pump body is made of G - 20 material, reliable and durable, made of precision cast iron, so the pump is beautiful, strong, durable. |
|
Mechanical seal A double mechanical seal consists of two seals in series. Superior wear-resistant silicon carbide mechanical seal to ensure optimal sealing effect. |
|
Characteristics 1. Vortex semi-open impellers, allowing passage of large physical dimensions. 2. Knife and ring material: 420 high chromium stainless steel, hardness HRC49 - 52, good wear resistance. |
|
